Affect / effect is another. Two wildly different words that I’ve never, ever had a problem with confusing, or even known that anyone else did, up until the Internet
I’ll put my hand up to that one. I struggle with these.
OED simplify it like this:
affect is “to influence or make a difference to”,
effect is “to bring something about as a result”.
which are fairly similar definitions.
And then you get into all the other definitions:
affect v.
have an effect on; make a difference to
touch the feelings of; move emotionally
pretend to have or feel (something)
use, wear, or assume (something) pretentiously or so as to make an impression on others
emotion or desire as influencing behaviour.
effect v.
cause (something) to happen; bring about
effect n.
a change which is a result or consequence of an action or other cause
an impression produced in the mind of a person
the lighting, sound, or scenery used in a play, film, or broadcast
personal belongings
In effect, you may effectively affect affection for effect. To the effect that I am affected. But that effect does not affect my effects.
I think.
